Extend rules

If you have a javascript configuration file for releases, you can pass a function in the array:

module.exports = {
    "plugins": [
    "@semantic-release/npm", 
    ["semantic-release-npm-deprecate-old-versions", {
      "rules": [
        customSupportFunction,
        "deprecateAll"
      ]
    }]
  ]
};

/**
 * @param {import('semver').SemVer} version
 * @param {Array<import('semver').SemVer>} allVersionsSortedLatestFirst
 * @returns {import('semantic-release-npm-deprecate-old-versions/rule').RuleResult}
 */
function customSupportFunction(version, allVersionsSortedLatestFirst){
  if (version.major === 4){
    // This version cannot be deprecated by other rules
    return { action: 'support' }
  }

  if (version.major === 3){
    // This version will be deprecated, and other rules
    // will not be applied
    return {
      action: 'deprecate',
      reason: 'Because the new version is awesome'
    }
  }

  // Let other rules decide
  return { action: 'continue' }
}

Supported vs deprecated versions

This plugin considers that either a version is supported, or it is deprecated.

Every rule computes a status on each version. Rules are applied in order, they have 3 possible outputs:

  • continue: the rule does not enforce the status of the given version, it is left to the next rules to decide the status
  • deprecate: the rule declares that the given version is deprecated, no further rule will be able to change this status
  • support: the rule declares that the given version is supported, as a consequence, no further rule will be able to change its status

Available rules and options

support-latest

This rule allows to declare a certain number of releases as supported. This rule does not apply to pre-releases.

Options

Configuration format

{
  numberOfMajorReleases?: number | "all",
  numberOfMinorReleases?: number | "all",
  numberOfPatchReleases?: number | "all"
}

All these options are optional. If a value is not set, the default value will apply

{
  "numberOfMajorReleases": 1,
  "numberOfMinorReleases": 1,
  "numberOfPatchReleases": 1
}

Examples

Use a number to configure the number of supported values

options: numberOfMajorReleases=2

2.0.1 2.0.0 1.0.2 1.0.1 1.0.0
support continue support continue continue

continue means that the status of a version is not fixed by this rule

Specify that all versions will be supported

options:

  • numberOfMajorReleases=1
  • numberOfMinorReleases="all"
2.2.0 2.1.0 2.0.1 2.0.0 1.0.0
support support support continue continue

continue means that the status of a version is not fixed by this rule

support-prerelease-if-not-released

This rule allows to declare a certain number of pre-releases as supported. This rule only applies to pre-releases.

Options

Configuration format

{
  numberOfPreReleases: number | "all",
}

Default configuration option

{
  "numberOfPreReleases": 1,
}

Examples

options: numberOfPreReleases=2

3.0.0-alpha.2 3.0.0-alpha.1 3.0.0-alpha.0 2.0.0 2.0.0-alpha.0
support support continue continue continue

options: numberOfPreReleases=2

2.0.0 2.0.0-alpha.0
continue continue

continue means that the status of a version is not fixed by this rule

In this example the version 2.0.0-alpha.0 is not marked as supported because the version 2.0.0 has been released.

deprecate-all

This rule deprecate all remaining versions (not previously marked as supported).

It is meant to be used at the end of rules declaration.

Options

This rule does not have any option

Examples

options: numberOfPreReleases=2

2.0.0 1.0.0
deprecate deprecate
